Question

One liter of ocean water contains 0.60 moles of salt. What volume of ocean water would contain 5.2 moles of salt

Answer 1

Answer:

8.67 liters of ocean water contains 5.2 moles of salt.

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

Then:

$x=\frac{c*b}{a}$

In this case the rule of three can be applied in the following way: if 0.60 moles of salt are contained in 1 liter of ocean water, then 5.2 moles of salt in how much volume is it contained?

$volume=\frac{5.2 moles of salt* 1 liter of ocean water}{0.60 moles of salt}$

volume= 8.67 liters

8.67 liters of ocean water contains 5.2 moles of salt.
